  • Water quality information in Hawaii

    New information about water quality is now available to people living, working, and playing near Hawaii. U.S. Integrated Ocean Observing System (IOOS®) partners located within the Pacific Islands region recently installed new nutrient sensors on two water quality buoys located at Kilo Nalu and near the Ala Wai outflow. These new sensors will provide early warning of storm runoff or other poor ...


  • Water Quality System

    Let me explain that our basic idea is how better to use the not many typologies (and parameters) of on-line sensors available on market to make low-cost sustainable intelligent monitoring. We all know that the total water quality is related to about fifty of quality measurement analytic parameters, but on-site and in on-line way, it is possible to detect only about ten electro-chemical or ISE ...

  • Harbour water quality improvements

    Cleaning up our stormwater is now the focus of efforts to further improve the water quality in the harbour and around Wellington's coast. We are already seeing the benefits of investing hundreds of millions of dollars in our sewerage and stormwater systems. Contamination levels in the harbour and around the South Coast have been dramatically reduced over the past 15 years. For example, in the ...

  • Water index to measure risk

    The World Resources Institute (WRI), in partnership with General Electric (NYSE: GE) and Goldman Sachs (NYSE: GS), has launched an initiative to measure water-related risks facing companies and their investors. The initiative will develop a Water Index as a standardised approach to identify and mitigate water-related corporate risk. The Index will offer one of the most expansive measures of ...


  • Optical water quality assessment

    Scientists at the U.S. Geological Survey (USGS) have proven that measuring fluorescence could improve source water monitoring during a study of the McKenzie River in Oregon.  The study was designed to assess the amount, type and source of dissolved organic carbon that exists in all sources of drinking water. Dissolved organic carbon can react with chlorine during water treatment and form ...

  • Water quality field device

    The benefits of a portable UV254 device, which utilises ultraviolet light at 254nm to quickly and accurately measure water quality while in the field, are discussed in an article available from Water Online. By conducting organic analysis in the field, water treatment professionals can react immediately to any problems. To take control of our water quality, we first need to know what"s in our ...

  • Putting a price on water quality

    One way to clean-up water pollution is to award 'credits' to facilities that reduce their emissions. These credits can then be traded with other facilities to compensate for pollution outputs. This controls overall pollutions levels, while creating an economic incentive to reduce emissions. Research using models that simulate water quality has been used to establish the value of these credits and ...

  • 3-D laser scanning: A new soil quality measurement

    Soil researchers pay close attention to bulk density, as it is one of the most common soil measurements and it is often used as a measure of soil quality. A soil’s bulk density can be indicative of the ease of root penetration, water movement, and soil strength. Measuring this value with traditional methods has been difficult in the past, but researchers have developed a new method using laser ...

  • A software system for the efficient control, administration and evaluation of automated water quality measuring networks

    ENMO®hydro represents the newest developments in dynamic, continuous and automated water quality monitoring and thus makes an important contribution to the early detection of disasters or accidents as well as to the evaluation of hazard potentials.

  • Water Quality Improves in Long Island Sound

    For the second summer in a row, concentrations of dissolved oxygen in Long Island Sound are higher than the long-term average, indicating improved water quality and improved ecological conditions for organisms that live in the Sound. Aquatic animals rely on oxygen that is dissolved in water to survive. When dissolved oxygen levels decline, this can cause some animals to move away, weaken, or even ...

  • `Smart` water quality sensor network wins iAward

    At last night's Australian Information Industry Association's annual awards in Melbourne, CSIRO was named winner of the 2010 iAward for research and development. CSIRO and Seqwater have developed Australia's largest integrated intelligent wireless sensor network, which is monitoring Lake Wivenhoe and its catchment. This supplies the majority of the region’s drinking water as part of the SEQ ...

  • Clam invasion threatens ecosystem balance and water quality

    Invasive alien species can have destructive effects on ecosystems. A recent study has shown that the invasive Asian clam (Corbicula fluminea) is reproducing at such a high rate in the River Minho Estuary, on the Portuguese/Spanish border, that it is not only threatening native species but also the quality of the river water. The functioning of freshwater ecosystems is easily unbalanced by human ...

  • EPA addresses water quality issues in Gloucester

    Boston, Mass.-- In order to advance healthy water quality in the coastal areas of Cape Ann near the City of Gloucester, EPA is proposing a draft decision to deny the extension of a waiver of Clean Water Act requirements that has allowed the City to discharge wastewater receiving only primary treatment from its wastewater treatment facility into Massachusetts Bay. Gloucester has applied to EPA for ...
